For what seems like forever I have been searching and posting for fog light grill nuts. Several members have been gracious enough to send me some. Some of those worked better that others. I gave up and decided to improvise. Instead of the #8 screw I'm using a M5 "J" nut with an M8 pan head screw with an internal torx drive. I agree that it is overkill but what the hell I'm finally done with my fog light grill install.

I just used clip-on speed nuts I picked up at my hardware store...

--DD

There's this place in Atlanta that will sell them to you. About $1.20 for each screw and clip and $20 shipping. If you're lucky, they'll have all 16 pieces. Otherwise, they'll send you 10 and charge you another $20 when the other 6 pieces come in...

Ask me how I know...

Or, you could just do what Dave did. You might as well, because that place in Atlanta? They're just getting them from McMaster-Carr.

Maybe you'll find it in here..

A few u-clip speed nuts and stainless sheet metal screws from my local Ace Hardware worked for me.

Ahh You didnt mention the FG bumper in the title.

I have a FG bumper and I JB-welded some "weld nuts" to the back of the bumper while it was off.
I had to use the actual covers to get them aligned correctly while the bumper was off the car.
That would be impossible with the bumper on the car.
